Although these auxiliary tasks were previously used in MTL models [1]}, [2]}, [3]}, [4]}, they were not used together in the same model.
Besides, the impact produced by adding each of the auxiliary tasks has not yet been studied.
Consequently, we show how each of them improves the latent space separation (Section REF ).
We evaluated each of these auxiliary tasks' contribution (quantitative results) to the SS task (see our ablation study in Section REF ).
